One of the things that made the III+ such
a useful GPS was that all the navigation screens had 26-user defined data
fields. This feature has been improved upon in the GPSmap 76.
The three main navigation screens can have 1-9 user defined data fields.
This is done with 1,2,3 rows of three per row small font data fields, giving
3,6,9 data fields. Or 1,2,3 rows of two per row medium font data
fields; giving 2,4,6 data fields. And finally 1 or 2 rows of one
large font data field per row; for 1 or 2 data fields.
